Modification from Noncommutative Inflation
Hong-Guang Zhang, Jie Ren, Xin-He Meng
We explore the noncommutative effect on single field inflation and compare with WMAP five-year data. First, we calculate the noncommutative effect from the potential and dynamical…
Observe the open universe in the sky?
Hong-Guang Zhang, Jie Ren, Xin-He Meng
We first review the related works on the observable consequence of landscape and the regulation of e-foldings during inflation. We focus on a branch of observable consequence of la…
Exact solutions of embedding the 4D Universe in a 5D Einstein manifold
Xin-He Meng, Jie Ren, Hong-Guang Zhang
One of the simplest way to extend 4D cosmological models is to add another spatial dimension to make them 5D. In particular, it has been shown that the simplest of such 5D models,…
Exploring trans-Planckian physics and the curvature effect by primordial power spectrum with WMAP five-year data
Jie Ren, Hong-Guang Zhang, Xin-He Meng
The vacuum inflation with a boundary condition specified at a short-distance scale in a generally primeval non-flat Universe, and implications of the correspondingly modified primo…
